The Girona team made a big mistake for letting one of their best player for last season leave the club when they know how important this season will be for them as they are going to be involved in the champions league competition which they have not had the opportunity to play for a long time, after watching their performance in their first match I made a conclusion that they were not going to be like the team we saw last season that was winning games and scoring goals in every match..
on the other hand it could be that selling out their best players after that performed exquisite for the club at the end of the season wasn't in their original agenda but as a means to recoup money for the club where it's lacking some of these growing clubs have to be forced to sell their best players especially when they are faced with a juicy offer from the elite clubs. And it's not that simple to quickly get a replacement, which is what makes them inconsistent with performance with each season. It would definitely be a challenging season for Girona as they will grapple to maintain a considerable form both in the champions league and their domestic league, and it's really going to affect their chances of making it far especially in the champions league where it's very competitive.
I would guess that it is a common thing for teams that are normally small but end up with a good result, they got some loans like savio that left, and they sold some players which means that they are not as good as last season but they are not in financial trouble.
All these smaller clubs end up doing the same thing, and I feel like they are really looking for something more sustainable, which is why they try to sell their players, because if they make money and use that money for further income, that means they can have a squad one day that they can afford and could be good. This period isn't that time just yet, but since they got taken over by City group, they are doing fine and I bet that they will continue to do well for a while longer.
